find the area asap i really need help 30 minutes left plzz
Answer:
45mm
Step-by-step explanation:
First, find the whole area of the square, which is 225 mm squared.
Then, we have to find the area of the shaded trapezoid. Remember, the area of the trapezoid is [tex]\frac{h(b^{1}+b^{2} }{2}[/tex]
We get the area of the trapezoid to be 180 mm.
We subtract 180 from 225 mm to get 45 mm as our answer.
2/3 + 3/4 + 4/2. If a fraction appears in your answer, it should be in simplified form.

This is my question.
Evaluate 12.3p + 11.7r when p = 6 and r = 7.
And then it’s written like this.
12.3(_)+11.7(_)=_+81.9
=_
Method:
First place the replace of p and r using brackets.
= 3(6) + 11.7(7)
3 times 6 is 18 and 11.7 times 7 is 81.9
= 18 + 81.9
add one and one together you get
= 99.9

y = 2x2-3x-5
PLEASE HELP AND SHOW WORK
(substitution)
Answer:
Step-by-step explanation:
y - x = -5
y = x-5
y = 2x² - 3x - 5
x-5 = 2x² - 3x - 5
2x² - 4x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2, 0
(x,y) = (2,-3), (0,-5)

A scoop of ice cream in the shape of a whole sphere sits in a right cone. the radius of the ice cream scoop is 2.5 cm and the radius of the cone is 2.5 cm. How tall must the height of the cone be to fit all the ice cream without spilling if it melts? SHOW ALL YOUR WORK!!!
Answer:
(At least) 10 centimeters.
Step-by-step explanation:
The radius of the ice cream scoop is 2.5 cm and the radius of the cone is also 2.5 cm.
We want to determine the height of the cone such that it will fit all of the ice cream when it melts without any spilling.
First, we will find the volume of the ice cream scoop. The volume for a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Since the radius is 2.5 cm, the volume of the full ice cream scoop is:
[tex]\displaystyle V=\frac{4}{3}\pi (2.5)^3[/tex]
Use a calculator:
[tex]V\approx 65.4498\text{ cm}^3[/tex]
The volume of a cone is given by:
[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]
The radius of the cone is 2.5 cm. Therefore:
[tex]\displaystyle V=\frac{1}{3}\pi(2.5)^2h=\frac{1}{3}\pi(6.25 h)=\frac{6.25\pi}{3}h[/tex]
The volume of the cone should be equal to the volume of the scoop. So:
[tex]\displaystyle 65.4498=\frac{6.25\pi}{3}h[/tex]
Solve for h:
[tex]\displaystyle h\approx 65.4498\Big(\frac{3}{6.25\pi}\Big)=10\text{ cm}[/tex]
The height of the cone should be (at least) 10 cm.

A cone has a volume of 98 cm.
The radius of the cone is 5.13 cm.
Work out an estimate for the height of the cone.
Answer:
3.56 cm.
Step-by-step explanation:
1/3 π r^2 h = V
1/3 π (5.13)^2 h = 98
h = 98 / (1/3 π (5.13)^2)
= 98 / 27.55899
= 3.556.
Cone is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
If the volume and radius of a cone are 98 cm and 5.13 cm.
The height of the cone is 3.56 cm.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h.
Example:
The cone has a radius of 2 cm and a height of 3cm.
The volume of a cone:
= 1/3 x 3.14 x 4 x 3
= 12.56 cm³
We have,
Cone:
Volume = 98 cm
Radius = 5.13 cm
Height of the cone = h
The volume of a cone:
V = 1/3πr²h
98 = 1/3 x π x (5.13)² x h
[ Take π = 3.14 ]
98 = 1/3 x 3.14 x 26.31 x h
Multiply 3 on both sides.
98 x 3 = 3.14 x 26.31 x h
Divide both sides by (3.14 x 26.31).
h = (98 x 3) / (3.14 x 26.31)
h = 294 / 82.61
h = 3.56 cm
Thus,
If the volume and radius of a cone are 98 cm and 5.13 cm.
The height of the cone is 3.56 cm.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Five times a number is 49 greater than the product of 2 and the opposite of the number.
Let the number is x:
From the statement "Five times a number is 49 greater than the product of 2 and the opposite of the number" we can frame a linear equation in one variable:
5x + 2x = 49 - 2x + 2x
After solving the above equation:
7x = 49
x = 49/7
x = 7
Thus, the number is 7 if five times a number is 49 greater than the product of 2 and the opposite of the number.
